The preponderance of time was spent in CALL/RETURN from "get one source character" routine. Great structure; lousy performance. I assume they never heard of macros.
CLIST performance was supposed to improve with TSO/E R2 and code reusable between Rexx/CLIST, but no fiche. What didn't your "small performance test" do? -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
